New C++ SDK for MCP Protocol Developed and Tested

By PulseAugur Editorial · [1 sources] ·

A new C++ SDK for the Model Context Protocol (MCP) has been developed, named mcp-cpp, to address the absence of an official C++ SDK. This SDK implements the latest 2026-07-28 specification, which differs significantly from previous versions by removing handshake and session IDs, and relying on client-initiated requests with MRTR (More Than Two Requests) for server input. The mcp-cpp SDK was tested against the official MCP conformance suite, revealing several bugs in the harness itself and highlighting differences in how older specifications handled server-initiated requests.
